The strength of The Fall of the Romanov Dynasty is its collection of significant historical scenes, and that is probably enough to enjoy the movie despite its half-hearted attempts at delivering political and social statements. Despite what the title of the movie would have you believe, this is not about the Romanov Dynasty, or rather it is only incidentally about the Romanov Dynasty. What this movie is about is the tumultuous time of human history in and around the World War, the Great War, the first war of its kind. It's a subject with such weight that it is best expressed through images and motion, making it ideal for a silent film.
An actual documentary of the Romanov Dynasty would need additional context to express its point, but hundreds of soldier marching across a crowd many times that size, or an enormous ship sinking, are both scenes that can be understood without narration. The bulk of the film is a collage of these sorts of scenes, and choosing to watch that is sufficient reason to watch the film, but unfortunately there's more. The film decided it needed a message and motive, and the one it chose is the evils of luxury and capitalism and they're disregard for the common man. For a person that subscribes to the ideology some of the imagery can incite righteous anger, for a person who doesn't some of the phrases used feel a lot like propaganda In either case the effect feels inconsequential when compared to the other subject of the film, similar to how the gravity of the moon is important not nearly as relevant as the gravity of the earth.
TL;DR: The movie has great historical footage of war and some of the important characters involved, but also scenes of workers, capitalists, estates, government officials, etc. that appear unnecessary and maybe even unwanted.
